    • PROBLEM TO BE SOLVED: To provide an anchoring method for a shear reinforcement material, which uses a grout material equipped with fluidity as in the case of downward construction, and which is excellent in economic efficiency and constructibility. SOLUTION: An insertion hole 2 is drilled sideways in a concrete structure 1. A box-shaped container 4 as a grout material storage means is installed on the drilling position outer surface of the insertion hole 2. An injection hose 6 is inserted from a top surface of the box-shaped container 4, and the hole is filled with the grout material 7. Air inside the insertion hole 2 leaks out along with the outflow of the grout material 7 in filling; when a liquid level of the grout material 7 in the box-shaped container 4 reaches the height of the insertion hole 2 or above, the inside of the insertion hole 2 is filled with the grout material 7; and a filled state is maintained under the liquid pressure. After a shear reinforcement 8 is inserted into the insertion hole 2, a portion in which the insertion hole 2 and the box-shaped container 4 communicate with each other, is closed. The grout material 7 is drawn out from a grout recovery port 10 of the box-shaped container 4, and the box-shaped container 4 is removed. When the grout material 7 in the insertion hole 2 is hardened, an outer frame 5 and a sheathing board 5a are removed. COPYRIGHT: (C)2010,JPO&INPIT
